Discontinued completely. That was the problem; it was a great product only conceptually. It never worked quite right (especially in the US market because of RF chipset limitations).

After seeing no mention of this on their website, I thought I would ask Riedel about this. Here's their response:

Andrew,

What is the saying? Believe half of what you see and none of what you hear. No, this product is not discontinued and there are no plans to discontinue it. Thanks for checking.

I can only recount what I've been told coming from Wuppertal.

I have been tasked to look for higher end wireless intercom systems for a local community theater group. They have the financial means to make this level of investment. I am quite familiar with the Telex BTR-200 (and 300) series units that operate in the VHF range.

They are not interested in that option since they currently have a BTR-300 that does not work well but particularly is subject to RF interference from somebody at the rental facility across the street. It seems that "some karaoke DJ" has a VHF unit and when he is there, it blasts through the BTR-300. There is not way to know when that will happen so the group's solution is to replace the BTR-300

That's a shame, that used to be my little trick to stay-clear of multi-channel microphone rigs because nobody seems to use VHF anymore!
(always bothered me that some dumbass with a $99 ancient plastic wireless product can force someone else to have to drop $100k+ just to keep going)
 
Re: Wireless Intercom Manufacturers (Vendors)?

:eek:~:-o~:eek:Riedel Acrobat is NOT discontinued. Be careful since in house wireless phones can stop it from working.

With Cell Com, in the USA Sprint PCS is on the same band so anyone with a Sprint cellphone interrupts it.

Tempest 2.4 gHz roaming is the most robust and easiest to implement over a wide area.

Telex BTR UHF does very well for a self contained theatre and gives better coverage than most with a single base and antenna.

Any chance you could clarify if it's only the European version?

Not quite. CellCom and the FCC certified Acrobat (not the one for the European market) operate in the unlicensed PCS band, 1.92-1.93GHz. This is the guardband between PCS broadband services (1.915-1.92GHz) and licensed PCS downlink band (1.93-1.99GHz), PCS block A (1.93-1.945GHz) being the first adjacent block on the high side. Cellular/PCS carriers do not have the same PCS blocks throughout the country with Verizon and Sprint each having block A in different markets. In those markets where Sprint has PCS block A, their out of band emissions (OOBE) emanating from their towers into the unlicensed PCS band are excessive and cause interference to that band. Markets where Verizon has block A do not exhibit nearly the same levels of OOBE. I've been hearing Sprint is beginning to clean it up.

When Acrobat was first designed it incorporated a European DECT band RF chipset (1.88-1.90GHz), and this is still the current Euro version. However, in the US, this encompasses the upper half of the licensed PCS uplink blocks (1.85-1.91GHz). So when the first [uncertified] Acrobat systems were brought to the left side of the pond they were clobbered by scores of more powerful nearby handsets transmitting to the tower(s).
 
Re: Wireless Intercom Manufacturers (Vendors)?

So I was randomly poking around the Telex web site and noticed their RPK-4 digital wireless matrix UHF intercom. Should the fact that I've never heard of it before tell me what I think it does? (That it's not a product with significant sales volume and probably best avoided).

Reading the manual it looks like you have to buy 1 base station per belt pack, is this correct?

Thanks

Re: Wireless Intercom Manufacturers (Vendors)?

Hey guys, I absolutely can't stand the latency in the DX200, etc from Clearcom/ HME. Let me describe the issue. SOmeone is next to me, we are both on com, I hear them directly mouth to ear and a short time later through the com. Very annoying. Of course the side tone latency is also an issue at times. I like RTS and a nice clean BTR800 rig. That being said does the Tempest have this issue? Is this issue due to the A/D - D/A or the fact that it's 2.4GHz? It's like talking to someone on a cell phone in the same room.

Mr Erskine, welcome! Whenever I get a strange look while installing my com ISO between the wired rig and the BTR, or a CCU, I just tell them YOU designed it and "they" leave me alone.

The RKP-4 is essentially a wireless four button key panel that's designed to connect directly to an ADAM matrix port, although there are several additional 4-wire analog I/Os. Since it's primary function is as a key panel it has to be a one-to-one and therefore one base to one beltpack. More expensive on a per channel basis than a BTR800/825. That said, having one or two channels available can be worthwhile for those TD's and coms tech who really do need to have access to more than just two intercom buses. There's about 3mS of latency.

IIRC Tempest does not have sidetone latency as the sidetone is generated internally in the beltpack.

All the current higher end digital intercom offerings have latency due not so much to the A/D and D/A conversions, but rather to the chosen transmission scheme, FHSS TDMA - Frequency Hopping Spread Spectrum Time Domain Multiple Access. Each beltpack is assigned a time slot to receive and to transmit. FHSS further has an inherent latency due to the cycling of the transmitter and waiting for the carrier to come up to full power with each hop.
 
Re: Wireless Intercom Manufacturers (Vendors)?

Hi guys. I would like to jump into this discussion with a couple of quick questions. Anyone have opinions about the Telex BTR80N system? What are the trade offs vs. the BTR800 in terms of sound quality and RF performance.

Thanks,
Jim W.
